Comment on Bye Intel, hi AMD! I’m done after 2 dead Intels

Looks like they didn’t have adequate cooling for their CPU, killed it… Then replaced it without correcting the cooling. If your CPU hits 3 digits, it’s not cooled properly.
That’s not the case. 100% for new CPUs, but also for old ones too.
My father’s old CPU cooler did not make good contact, got lose in one corner some how, and the system would throttle (fan at 100% making noise and PC run slow). After i fixed it, in one of my visits, CPU was working fine for years.
System throttles or even shuts down before any thermal damage occures (at least when temperatures rise normally).
Pretty much anything with a heat spreader should be impossible to accidentally kill. Bare die? May dog have mercy on your soul.
What if it hits around 90°C during Vulkan shader processing? 😅 Otherwise like 42–52 idle. How’s that? I’m wondering if my cooling is sufficient.
It’s fine, modern CPUs boost until they either hit amperage, voltage, or thermal constraints, assuming the motherboard isn’t behaving badly then the upper limits for all of those are safe to be at perpetually.
If you’re talking about the Steam feature you can safely turn it off, any modern AMD GPU running mesa radv (the default driver in most distros) should be sufficient to process shaders in real-time thanks to ACO.
What does it mean to “process shaders in real-time”? Wouldn’t it be objectively faster to process them ahead-of-time? Even if it’s only slightly faster while running the game?
I mean processing takes like a minute or so, so it’s no big deal. I’m just curious for the fun of it, if I can compile it on the GPU. Not sure it’s even possible.
What does it mean to “process shaders in real-time”?
Processing them as they’re loaded, quickly enough that there’s no noticeable frame drop. Usual LLVM based shader compilers aren’t fast enough for that but ACO is specifically written to compile shaders for AMD GPUs and makes this feasible.
Pre-compilation would in theory always yield higher 1% lows yes, but it’s not really worth the time hit anymore especially for games that constantly require a new cache to be built or have really long compilation times.
I think the one additional thing Steam does in that step is transcoding videos so they can be played back with Proton’s codec set but using something like Proton-GE, Proton-cachyos or Proton-EM solves this too.
Disclaimer: I don’t know how the deeply technical stuff of this works so this might not be exact.
How far back does that go? My AMD 6000 series GPU probably doesn’t need it, but what about my old laptop APU (3500U?).
AMDs 7000 series CPUs were designed to boost until they hit 95c, then maintain those temps. 9000 series behaves differently for boosting, but the silicon can handle it.
Okay cool, then I feel more confident. This is only my second build, ever, so I’m a little bit nervous. I didn’t buy any extra fans apart from the ones that came with my case. But I did get that beasty Noctua gen 2 air cooler, and it seems to be holding so far, even in the hot summer air.
Slight under volt, or upgrade cooler. 90c is too hot sustainably. Idle high 40s to 50s is not the best. Find a better air cooler or use a 240 AIO atleast.
I did some quick research.
The idle temperature for the AMD Ryzen 9 9950X3D can vary, but many users report it idling between 50-60°C, which is considered normal for this processor.
Under load, the Ryzen 9 9950X3D can reach temperatures up to 90°C, which is within the acceptable range for this CPU.
I feel confident now. My CPU and cooling seems perfectly nominal. 😌👌
If your running that CPU then you almost certainly have done research or have money. Either way. Enjoy the setup you’ve got a good cooler and CPU it seems.
Not true, 95C is the rated safe operating temperature
95c is damn near boiling at 203f. That is too hot to sustain any good longevity of a part, and any good workload for any component in a PC. That is a lot of heat. You will not get the best performance for a processor at its maximum temperatures running it like that all the time or even close to its max operating temp. I’m not saying you can’t hit that number but ideally you really really shouldn’t.
So what I said I think stands. Upgrade to a better air cooler and if need be a water cooler at least a 240AIO nothing smaller period. Keep temps lower and parts last longer. Performance boosts during core loads hold clocks longer. No question.
damn… its sitting at 301 Kelvin currently…

If your CPU hits 3 digits, therm throttling isn’t working properly, because it should kick in before it hits that point.
frongt@lemmy.zip 2 days ago
The article (or one of the linked ones) says the max design temperature is 105°C, so it doesn’t throttle until it hits that.
Which makes me think it should be able to sustain operating at that temperature. If not, Intel fucked up by speccing them too high.
sugar_in_your_tea@sh.itjust.works 2 days ago
I’d expect it to still throttle before getting to 105C, and then adjust to maintain a temp under 105C. If it goes above 105C, it should halt.
frongt@lemmy.zip 2 days ago
Then you misunderstand the spec. That’s the max operating temperature, not the thermal protection limit. It throttles at 105 so it doesn’t hit the limit at 115 or whatever and shut down. I can’t find a detailed spec sheet that might give an exact figure.

Why? It’s designed to run up to 105c.
I think it was when AMDs 7000 series CPUs were running at 95c and everyone freaked out that AMD came out and said that the CPUs are built to handle this load 24/7 365 for years on end.
And it’s not like this is new to Intel. Intel laptop CPUs have been doing this for a decade now.

My intel mac’s cpu (i5-5250U) throttles to maintain 105 C

When I overclock this old chip (which it was built for) it can hit over 100 with proper cooling. Some chips are hot as fuck. I think this one shuts off at 105.
